Congratulations, you did it in a very short time.
Just a question, regarding the muxsel_hook:
For future implementations and/or new cards add, does it breaks binary
compatibility ?
should we use the same function, just with the proper mux change code for
another board w/ this kind of device ? I think its ok, dont see a problem
there...
Regards.
